She looks like she doesn’t want photographic evidence they dated. She’s probably too young/not experienced/not assertive enough to tell him she’s really not interested. After a couple of weeks of living in terror of him emotionally and physically smothering her 24/7 and the stress of trying to avoid him prevents her from eating or sleeping, she’ll finally use some desperate, lame excuse why they can’t date. He’ll cry, and she’ll have to spend the next few weeks washing the sickening smell of his cheap, overpowering cologne out of all of her clothes.
I think you guys are reading it all wrong, in the bottom two, that we can’t see, her face is facing towards him, kissing him, but she’s still covering her face, I think she just doesn’t want her face in the photo.
